NOTE: Although swinstall is illustrated here, the install can use one or more of swinstall with remsh (port 514), NFS (ports 49152–65535), ftp data (port 20), and ftp (port 21).

7.The server pings the client with an ICMP type 8 echo request. The client answers the ping with an ICMP type 0 echo reply. Files required for bootsys are transferred from the server to the client. These files are transferred with remsh by default, or by ssh if the bootsys -Soption is used.

8.The kernel, file system, and required files are downloaded from the server to the client, then the client is booted. These files are transferred with rcp by default, or by scp if the bootsys -Soption is used.

NOTE:

The client can specify to use privileged ports (1–1023) or not via the ssh_config directive. The default is non-privileged ports. If you want to configure ssh to use privileged ports, you have to make the client an suid program.
